Challenges in the Public-Private Partnership Process for the Utilization of Vacant Public Employee Housing: A Case Study of the Social Experiment at Koba H Apartment in Nagasaki

This paper explores new possibilities for public-private partnerships in utilizing vacant public assets. It does so by examining a social experiment in Nagasaki involving the collaborative use of vacant public employee housing, and by identifying the challenges that emerged during the implementation process. Through interviews with relevant stakeholders, the study identifies a four-stage coordination process and analyzes 12 key issues. These are consolidated into five overarching challenges: misalignment between policy design and business feasibility, asymmetry in risk allocation, differences in administrative mindsets, the nature and capacity of private actors, and reliance on personal relationships.
